Even when there is no traffic. This adds stress on the memory manager. The handling of compound pages is also less trivial for the memory manager and not using them will make the allocation code run faster although I didn't really measure. Eric also pointed out that having huge buffers with little data in them is not very nice towards the TCP stack since the truesize of the skb is huge. This doesn't allow TCP to have a big Rx window. See https://patchwork.kernel.org/patch/2167711/ for details. Note that very few vendors will actually send A-MSDU. Disable this feature by default.

Investigating this problem more closely we found that this write-back isn't really ordered very well with respect to other DMA traffic. Therefore, it sometimes happened that the write-back occurred after unmapping the command again which is clearly an issue and could corrupt the next allocation that goes to that spot, or (better) cause IOMMU faults. To fix this, allocate coherent memory for the first 16 bytes of each command, containing the write-back part, and use it for all queues. All the dynamic DMA mappings only need to be TO_DEVICE then. This ensures that even when the write-back happens "too late" it can't hit memory that has been freed or a mapping that doesn't exist any more. Since now the actual command is no longer modified, we can also remove CMD_WANT_HCMD and get rid of the DMA sync that was necessary to update the scratch pointer.

In this case, the frame won't be sent any more. So we need to move the window on the recipient side. This is done by a BAR. Now if we are in the following case: 10, 12 and 13 are ACKed and 11 isn't. 10 11 12 13. V X V V Then, 11 will be sent 16 times as an MPDU (as oppsed to A-MPDU). If this failed, we are entering the flow described above. So we need to send a BAR with ssn = 12. But in this case, the scheduler will tell us to free frames up to 13 (included). So, it is perfectly possible to get a failed single Tx response on an AMPDU queue that makes the scheduler's ssn jump by more than 1 single packet.

After a QH has been unlinked from the async schedule and the corresponding IAA interrupt has occurred, the controller is not supposed access the QH and its qTDs. There certainly shouldn't be any more DMA writes to those structures. Nevertheless, Intel's controllers have been observed to perform a final writeback to the QH's overlay region and to the most recent qTD. For more information and a test program to determine whether this problem is present in a particular controller, see http://marc.info/?l=linux-usb&m=135492071812265&w=2 http://marc.info/?l=linux-usb&m=136182570800963&w=2 This patch works around the problem by always waiting for two IAA cycles when unlinking an async QH. The extra IAA delay gives the controller time to perform its final writeback. Surprisingly enough, the effects of this silicon bug have gone undetected until quite recently.

In a couple of places, the driver compares the DMA address stored in a QH's overlay region with the address of a particular qTD, in order to see whether that qTD is the one currently being processed by the hardware. (If it is then the status in the QH's overlay region is more up-to-date than the status in the qTD, and if it isn't then the overlay's value needs to be adjusted when the QH is added back to the active schedule.) However, DMA address in the overlay region isn't always valid. It sometimes will contain a stale value, which may happen by coincidence to be equal to a qTD's DMA address. Instead of checking the DMA address, we should check whether the overlay region is active and valid. The patch tests the ACTIVE bit in the overlay, and clears this bit when the overlay becomes invalid (which happens when the currently-executing URB is unlinked).

If the MAC is waiting for completion indications for 2 DMA write requests into Host memory (e.g. descriptor writeback or Rx packet writing) and the indications occur while the clock is stopped, both indications will be missed by the MAC causing the MAC to wait for the completion indications and be unable to generate further DMA write requests. This results in an apparent hardware hang. Work-around the issue by disabling the de-assertion of the clock request when 1000Mbps link is acquired (K1 must be disabled while doing this).

As a result, if you boot with USB cable on and load g_ether, the connection does not work as the code thinks the cable is off and the phy gets powered down immediately. This is a major regression in 3.9-rc1. So the proper check should be: exit if _glue is NULL, but if it's initialized we memorize the status, and then check if the musb core is ready.

After EEH core finishes the reset, the driver callback (be_eeh_reset) is called and wait the firmware to complete POST successfully. The original code would return with error once detecting failure during POST stage. That seems not enough. The patch forces the driver (be_eeh_reset) to wait the firmware completes POST until timeout, instead of returning error upon detection POST failure immediately.

The problem we are hitting is that the module xen-acpi-processor which uses the ACPI's functions: acpi_processor_register_performance, acpi_processor_preregister_performance, and acpi_processor_notify_smm fails at acpi_processor_register_performance with -22. Note that earlier during bootup in arch/x86/xen/setup.c there is also an call to cpufreq's API: disable_cpufreq(). This is b/c we want the Linux kernel to parse the ACPI data, but leave the cpufreq decisions to the hypervisor. In v3.9 all the checks that d5aaffa9dd531c978c6f3fea06a2972653bd7fc8 added are now hit and the calls to cpufreq_register_notifier will now fail. This means that acpi_processor_ppc_init ends up printing: "Warning: Processor Platform Limit not supported" and the acpi_processor_ppc_status is not set. The repercussions of that is that the call to acpi_processor_register_performance fails right away at: if (!(acpi_processor_ppc_status & PPC_REGISTERED)) and we don't progress any further on parsing and extracting the _P* objects. The only reason the Xen code called that function was b/c it was exported and the only way to gather the P-states. But we can also just make acpi_processor_get_performance_info be exported and not use acpi_processor_register_performance. This patch does so. Acked-by: Rafael J.

The commit effectively added a large number of Huawei devices to the deprecated usb-storage mode switching logic. Many of these devices have been in use and supported by the userspace usb_modeswitch utility for years. Forcing the switching inside the kernel causes a number of regressions as a result of ignoring existing onfigurations, and also completely takes away the ability to configure mode switching per device/system/user. Known regressions caused by this: - Some of the devices support multiple modes, using different switching commands. There are existing configurations taking advantage of this. - There is a real use case for disabling mode switching and instead mounting the exposed storage device. This becomes impossible with switching logic inside the usb-storage driver. - At least on device fail as a result of the usb-storage switching command, becoming completely unswitchable. This is possibly a firmware bug, but still a regression because the device work as expected using usb_modeswitch defaults. In-kernel mode switching was deprecated years ago with the development of the more user friendly userspace alternatives. The existing list of devices in usb-storage was only kept to prevent breaking already working systems. The long term plan is to remove the list, not to add to it.

Normally this would be done after the next irq for the underlying device is handled. However in situations where we have no outstanding request we have to schedule the request function for a later time. This is determined using an internal counter of requests issued to the hardware. In some cases where we give a request back to the block layer unhandled the number of queued requests was not adjusted. Fix this class of failures by adjusting queued_requests in all functions used to give a request back to the block layer.

It removes pci_save_state() from __e1000_shutdown() for normal adapters, PCI bus callbacks pci_pm_*() will do all this for us. Now __e1000_shutdown() switches to D3-state only quad-port adapters, because they needs quirk for clearing false-positive error from downsteam pci-e port. pci_save_state() now called after clearing bus-master bit, thus __e1000_resume() and e1000_io_slot_reset() must set it back after restoring configuration space. This patch set get_link_status before calling pm_runtime_put() in e1000_open() to allow e1000_idle() get real link status and schedule first runtime suspend. This patch also enables wakeup for device if management mode is enabled (like for WoL) as result pci_prepare_to_sleep() would setup wakeup without special actions like custom 'enable_wakeup' sign.

When the mlx4_core is activating its "legacy mode" (e.g when running in SRIOV mode) w.r.t to EQs/IRQs usage, comp_pool becomes zero and we're crashing on divide by zero alloc_cpu_rmap. Fix that by enabling RFS only when running in non-legacy mode. Reported-by: Yan Burman Cc: Kleber Sacilotto de Souza Signed-off-by: Amir Vadai Signed-off-by: Or Gerlitz Signed-off-by: David S.

This is due to tp->link_up flag never becoming true causing tg3_periodic_fetch_stats() to return. The link_up flag was being updated in tg3_test_and_report_link_chg() after setting up the phy. This function however, is not called for phylib devices since the driver does not do the phy setup. This patch moves the link_up flag update into the common tg3_link_report() function that gets called for phylib devices as well for non phylib devices when the link state changes. To avoid updating link_up twice, we replace tg3_carrier_...() calls that are followed by tg3_link_report(), with netif_carrier_...(). We can then remove the unused tg3_carrier_on() function.

This can been seen in the original post. 2) A serial quirk isn't needed as these cards have no memory in BAR0 which makes pci_plx9050_init just return.

This means any existing usage of the 8259. module parameters or as a kernel command line switch is now broken, as the 8250_core driver doesn't parse options belonging to something called "8250". To solve this, we redefine the module options in a dummy function using a redefined MODULE_PARAM_PREFX when built into the kernel. In the case where we're building as a module, we provide an alias to the old 8250 name. The dummy function prevents compiler errors due to global variable redefinitions that happen as part of the module_param_ macro expansions.

I was too lazy to bisect for bad commit;) Reading the code I found problematic kthread_should_stop call from netlink connector which causes the oops. After applying a patch, I've been testing owfs+w1 setup for nearly two days and it seems to work very reliable (no hangs, no memleaks etc). More detailed description and possible fix is given below: Function w1_search can be called from either kthread or netlink callback. While the former works fine, the latter causes oops due to kthread_should_stop invocation. This patch adds a check if w1_search is serving netlink command, skipping kthread_should_stop invocation if so.

One effect of this change was that the advertisement register would not be updated if autoneg is turned off. This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults to advertise only 10Mb Full duplex. But with autoneg disabled, it needs the configured speed enabled in the advertisement register to link up.

Using the number of endpoints in the default altsetting to decide whether the function use one or two interfaces is wrong. Other altsettings may provide more endpoints. With Gobi 1K devices, USB interface #3's altsetting is 0 by default, but altsetting 0 only provides one interrupt endpoint and is not sufficent for QMI. Altsetting 1 provides all 3 endpoints required for qmi_wwan and works with QMI. Gobi 1K layout for intf#3 is: Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 0 Endpoint Descriptor: Interrupt IN Interface Descriptor: 255/255/255 bInterfaceNumber 3 bAlternateSetting 1 Endpoint Descriptor: Interrupt IN Endpoint Descriptor: Bulk IN Endpoint Descriptor: Bulk OUT Prior to commit bd877e4, we would call usbnet_get_endpoints before giving up finding enough endpoints. Removing the early endpoint number test and the strict functional descriptor requirement allow qmi_wwan_bind to continue until usbnet_get_endpoints has made the final attempt to collect endpoints. This restores the behaviour from before commit bd877e4 without losing the added benefit of using a single bind function. The driver has always required a CDC Union functional descriptor for two-interface functions. Using the existence of this descriptor to detect two-interface functions is the logically correct method.

In that patch I overlooked a few things. The original documentation for NAND_NO_READRDY included "True for all large page devices, as they do not support autoincrement." I was conflating "not support autoincrement" with the NAND_NO_AUTOINCR option, which was in fact doing nothing. So, when I dropped NAND_NO_AUTOINCR, I concluded that I then could harmlessly drop NAND_NO_READRDY. But of course the fact the NAND_NO_AUTOINCR was doing nothing didn't mean NAND_NO_READRDY was doing nothing... So, NAND_NO_READRDY is re-introduced as NAND_NEED_READRDY and applied only to those few remaining small-page NAND which needed it in the first place.

In order to avoid keeping multiple QHs in an unusable intermediate state, that commit changed unlink_empty_async() so that it unlinks only one empty QH at a time. However, when the EHCI root hub is suspended, _all_ async QHs need to be unlinked. ehci_bus_suspend() used to do this by calling unlink_empty_async(), but now this only unlinks one of the QHs, not all of them. The symptom is that when the root hub is resumed, USB communications don't work for some period of time. This is because ehci-hcd doesn't realize it needs to restart the async schedule; it assumes that because some QHs are already on the schedule, the schedule must be running. The easiest way to fix the problem is add a new function that unlinks all the async QHs when the root hub is suspended. This patch should be applied to all kernels that have the 6e0c3339a6f1 commit.

This caused a regression for users wanting to use NCM. Devices implementing NCM backwards compatibility according to section 3.2 of the MBIM v1.0 specification allow either NCM or MBIM on a single USB function, using different altsettings. The cdc_ncm and cdc_mbim drivers will both probe such functions, and must agree on a common policy for selecting either MBIM or NCM. Until now, this policy has been set at build time based on CONFIG_USB_NET_CDC_MBIM.

The regression was introduced in 3.6 kernel for cleaning up the mode clock handling code in intel_dp.c by the commit [71244653: drm/i915: adjusted_mode->clock in the dp mode_fix]. In the past, the clock of the reference mode was modified in intel_dp_mode_fixup() in the case of eDP fixed clock, and this clock was used for calculating in intel_dp_set_m_n(). This override was removed, thus the wrong mode clock is used for the calculation, resulting in a psychedelic smoking output in the end. This patch corrects the clock to be used in the place. v1->v2: Use intel_edp_target_clock() for checking eDP fixed clock instead of open code as in ironlake_set_m_n().

Previously their definitions were reversed. Even though there are no ill effects being observed from the swapped definitions (because IMAN_IP is RW1C and in legacy PCI case we come in with it already set to 1 so it was clearing itself even though we were setting IMAN_IE instead of IMAN_IP), we should still correct the values. This patch should be backported to kernels as old as 2.6.36, that contain the commit 4e833c0b87a30798e67f06120cecebef6ee9644c "xhci: don't re-enable IE constantly".

The aim of this commit was to ensure that ROM images were available on some Apple systems that don't expose the GPU ROM via any other source. In this case, UEFI appears to have provided a broken ROM image that we were using even though there was a perfectly valid ROM available via other sources. The simplest way to handle this seems to be to just re-order pci_map_rom() and leave any firmare-supplied ROM to last.

It turns out though that on many systems this leads to spurious interrupts being generated, long after the register write to disable the IRQs has been issued.

So by all indications it seems like gmbus is able to generate a legacy (shared) interrupt in MSI mode on some configurations. I've tried to reproduce this and the differentiating thing seems to be that on unaffected systems no other device uses irq 16 (which seems to be the non-MSI intel gfx interrupt on all gm45). I have no idea how that even can happen. To avoid tempting this elephant into a rage, just disable gmbus interrupt support on gen 4. v2: Improve the commit message with exact details of what's going on. Also add a comment in the code to warn against this particular elephant in the room. v3: Move the comment explaing how gen4 blows up next to the definition of HAS_GMBUS_IRQ to keep the code-flow straight.

It has been possible for handle_stripe_dirtying to be called when there isn't actually any work to do. It then calls schedule_reconstruction() which will set R5_LOCKED on the parity block(s) even when nothing else is happening. This then causes problems in do_release_stripe(). So add checks to schedule_reconstruction() so that if it doesn't find anything to do, it just aborts. This bug was introduced in v3.7, so the patch is suitable for -stable kernels since then.

However, when device-mapper is used to create RAID4/5/6 arrays, the mddev->gendisk and mddev->queue fields are not setup. Therefore, calling things like trace_block_bio_remap will cause a kernel oops. This patch conditionalizes those calls on whether the proper fields exist to make the calls. (Device-mapper will call trace_block_bio_remap on its own.) This patch is suitable for the 3.8.y stable kernel.

A number of problems can occur due to races between resync/recovery and discard. - if sync_request calls handle_stripe() while a discard is happening on the stripe, it might call handle_stripe_clean_event before all of the individual discard requests have completed (so some devices are still locked, but not all). Since commit ca64cae96037de16e4af92678814f5d4bf0c1c65 md/raid5: Make sure we clear R5_Discard when discard is finished. this will cause R5_Discard to be cleared for the parity device, so handle_stripe_clean_event() will not be called when the other devices do become unlocked, so their ->written will not be cleared. This ultimately leads to a WARN_ON in init_stripe and a lock-up. - If handle_stripe_clean_event() does clear R5_UPTODATE at an awkward time for resync, it can lead to s->uptodate being less than disks in handle_parity_checks5(), which triggers a BUG (because it is one). So: - keep R5_Discard on the parity device until all other devices have completed their discard request - make sure we don't try to have a 'discard' and a 'sync' action at the same time. This involves a new stripe flag to we know when a 'discard' is happening, and the use of R5_Overlap on the parity disk so when a discard is wanted while a sync is active, so we know to wake up the discard at the appropriate time. Discard support for RAID5 was added in 3.7, so this is suitable for any -stable kernel since 3.7.

The callback routine should not be invoked with a pointer to the old driver; doing so can cause problems (such as use-after-free accesses in net2280).

The effect of this was that removal of a shared block could result in the space maps thinking the block was no longer used. More concretely, if you have a thin device and a snapshot of it, sending a discard to a shared region of the thin could corrupt the snapshot. Thinp uses a 2-level nested btree to store it's mappings. This first level is indexed by thin device, and the second level by logical block. Often when we're removing an entry in this mapping tree we need to rebalance nodes, which can involve shadowing them, possibly creating a copy if the block is shared. If we do create a copy then children of that node need to have their reference counts incremented. In this way reference counts percolate down the tree as shared trees diverge. The rebalance functions were incrementing the children at the appropriate time, but they were always assuming the children were internal nodes. This meant the leaf values (in our case packed block/flags entries) were not being incremented.

This patch fixes this by transferring the prefetch to a worker thread and skipping it completely if kmalloc fails. If generic_make_request is called recursively, it queues the I/O request on the current->bio_list without making the I/O request and returns. The routine making the recursive call cannot wait for the I/O to complete. The deadlock occurs when one thread grabs the bufio_client mutex and waits for an I/O to complete but the I/O is queued on another thread's current->bio_list and is waiting to get the mutex held by the first thread. The fix recognises that prefetching is not essential. If memory can be allocated, it queues the prefetch request to the worker thread, but if not, it does nothing.

Currently, dm core sends the cache target two bios, one for the origin device and one for the cache device and these are processed in parallel. This patch avoids the race by changing the code back to a simpler (slower) implementation which processes the two writes in series, one after the other, until we can develop a complete fix for the problem. When the cache is in writethrough mode it needs to send WRITE bios to both the origin and cache devices. Previously we've been implementing this by having dm core query the cache target on every write to find out how many copies of the bio it wants. The cache will ask for two bios if the block is in the cache, and one otherwise. Then main problem with this is it's racey. At the time this check is made the bio hasn't yet been submitted and so isn't being taken into account when quiescing a block for migration (promotion or demotion). This means a single bio may be submitted when two were needed because the block has since been promoted to the cache (catastrophic), or two bios where only one is needed (harmless). I really don't want to start entering bios into the quiescing system (deferred_set) in the get_num_write_bios callback. Instead this patch simplifies things; only one bio is submitted by the core, this is first written to the origin and then the cache device in series. Obviously this will have a latency impact. deferred_writethrough_bios is introduced to record bios that must be later issued to the cache device from the worker thread. This deferred submission, after the origin bio completes, is required given that we're in interrupt context (writethrough_endio).

The workaround goes through two IAA cycles for each QH being unlinked. During the first cycle, the QH is not added to the async_iaa list (because it isn't fully gone from the hardware yet), which means that list will be empty. Unfortunately, I forgot to update the IAA watchdog timer routine. It thinks that an empty async_iaa list means the timer expiration was an error, which isn't true any more. This problem didn't show up during initial testing because the controllers being tested all had working IAA interrupts. But not all controllers do, and when the watchdog timer expires, the empty-list check prevents the second IAA cycle from starting. As a result, URB unlinks never complete. The check needs to be removed. Among the symptoms of the regression are processes stuck in D wait states and hangs during system shutdown.

Once the bootloader would load the selected kernel, the screen would go black. At first it was assumed that the mgag200 kms driver was hanging. But after setting up the grub serial output, it was seen that the driver was being loaded properly. After trying serval monitors, one finaly displayed the message "Frequency Out of Range". By comparing the kms pll algorithm with the previous mgag200 xorg driver pll algorithm, discrepencies were found. Once the kms pll algorithm was modified, the expected pll values were produced. This fix was tested on several monitors of varying native resolutions.

It occurs in all 3.8.x versions and the mainline version as of 2/4. The issue does not occur with the 3.7.x builds. There are two methods for accessing the watchdog registers. 1. Re-programming a resource address obtained by allocate_resource() to chipset. 2. Use the direct memory-mapped IO access. The method 1 can be used by all the chipsets (SP5100, SB7x0, SB8x0 or later). However, experience shows that only PC with the SB8x0 (or later) chipsets can use the method 2. This patch removes the method 1, because the critical problem was found. That's why the watchdog timer was able to be used on SP5100 and SB7x0 chipsets until now.

Instead of elaborating a workaround for that specific SoC or IP version, we simply use a software variable to store the Interrupt Mask Register and modify it for each enabling/disabling of an interrupt. The overhead of this is negligible anyway. The interrupt mask register (IMR) for the RTC is broken on the AT91SAM9x5 sub-family of SoCs (good overview of the members here: http://www.eewiki.net/display/linuxonarm/AT91SAM9x5 ). The "user visible effect" is the RTC doesn't work. That sub-family is less than two years old and only has devicetree (DT) support and came online circa lk 3.7 . The dust is yet to settle on the DT stuff at least for AT91 SoCs (translation: lots of stuff is still broken, so much that it is hard to know where to start). The fix in the patch is pretty simple: just shadow the silicon IMR register with a variable in the driver. Some older SoCs (pre-DT) use the the rtc-at91rm9200 driver (e.g. obviously the AT91RM9200) and they should not be impacted by the change. There shouldn't be a large volume of interrupts associated with a RTC.
